It is an object of this invention to gen erally improve the construction and operation of plumbing fixtures of' that type which is termed in the art as Va ilush valve, although it is to beunderstood that the principles thereof may be used in connection with other devices;

Another object of ,thisV invention resides in the provision of a flush valve operating means which is capable of being readily installed in flush tanks now in use as well at the time of their manufacture.

ceive a iloat valvelO which is normally heldy With the above and other objects in view which will appearl as thev description Vproceeds, my invention resides in the novel construction, combination and arrangement oi? changes in the precise embodiment of thek hereindisclosed invention may be made as come within the scope of the claims.

In the accompanying drawing, l have illustrated one complete example of the physical embodiment ot my invention Vconstructed according to the best model have so far devised for the practical application of the principles thereof, and in which:

The single view is a sectional one through the lower or bottom'portion of a. iush tank illustrating the installation of my improved flush valve operating means, part of the operatingmeans'being in section and part thereof being in side elevation.

Referring now more particularly to the accompanying drawing, the numeral 5 represents the bottom wall of a' flushA tank which is apertured, as at 6, to receive the nippled end 7 of an outlet 8, provided with a valve seat 9 at its inner end. The valvev i seat isof approximately bowl shape'to rein engagement with the seat to close the outlet by the body of water within the tank,

the valve, upon being disengaged, from its seat by the means to be later described, floating on the top, of the water and reseating as the tank'einpties. Y

The outlet is preferably cast and secured in position by a sleeve 11l threaded on its nippled end 7 in the manner illustrated in.

the drawing. Supported vertically` in the tank, preferably vfrom a lug 12 formed on the seat, is a postor standard 13 which mounts means for guiding the valve 10 in its movement to and from outlet. Y

l Fixed to the valveand extended upwardly therefrom is alguide rod or stem 14 which is slidable in a sleeve 15 formed on the louter end of a guide arm 16 adjustably supported from the standard13 by an attaching Vcollar- 17 adapted to be releasibly secured thereto by a set screw or other means 18. The guide arm 16 is'adjustable by a turnbuckle 19 to align the sleeve 15 with the axis ot vthe outlet. f l

1When in a. lower position closing the outlet, the guide rod upper endg20 extends above the sleeve 15 a distance substantially equal to the length of an armature 2l,

a position closingthe through which the upper' end Vot the rod Y slidablygpasses. l'lhe armature 21 is soft iron or other magnetic material4 and may be of hollow construction closed at its ends as illustrated.

Also supported from the standard a solenoid coil 22 which is wound on a nonmagnetic sleeve or hollow core 23 and conlined in a casing 24 from .which attaching arms 25 extend to sleeves 26 fixed to the over at its ends to the core by the rings 28 to Y protectthe coil fromthe water within the tank'and the sleeves 17 and 26 are so ad- ]ustedon the standard that, with the valve closed, the armature rests on the sleeve 15 with its mass positioned below the magnetic center of the solenoid. p Y f,

The solenoid is connected with a source of energy 29 by conductors 30 in the circuit of which a switch 31 of 'a suitable type is included, so'that the closing of switch 31 connects the solenoid with its source of energy. As the solenoid is energized by con-y nection with its source of current, the armature is quickly attracted into thecore 23'to tend to center its mass with respect to the magnetic center of the solenoid. The upper end 2O ofthe stem 14 being enlarged or bentv over the armature, causes the armature to imi] raise the valve as it is attracted into the solenoid, freeing the outlet.v The valve 10 is of the iloat or ,buoyantv type held in engagement with` its seat by the inlet, not shown.

weight of the water in the tank and as it is freed ofthe outlet by the attraction of the armature to the solenoid it fioatson the top of the water until the tank is emptied when it again engages its seat and is held there by the water enteringthe tank through the The armature 21 being freely slidable on the rod lei permits the operation of the device by but an instant energization of the solenoid thus reducing the current consumption to a minimum and preventing destructive overheating` of the` Y solenoid and is closed at its lower end as at body 2l encased in a brass or other non#A corrosive body From the foregoing description taken in connection with the accompanying drawing, it will be readily apparent to those slilled I in the art to which an invention of this character appertalns that I have provided a flushV tanlr valver which is eflicient in operation, simple in construction 'and wlnch may be applied to flush tanlrs now 1n use orto tanks at their time of manufacture.

WV hat I claim as'my invention is l. In a device of the character described, any outlet, a valve member normally closing the outlet, a solenoid disposed above the outlet, an armature normally resting in an inactive position and adapted to be attracted Ito the solenoid upon energiZat-ionl thereof,

and a connection between the valve member and armature permitting` a limited movement of one with respect to the other, whereby, with the valve member in position clos- 50,

ing` the outlet, a movement of the armature by energization kof the solenoid moves the valve member with it free of the out-let.
